Question

De broglie wavelength formula for neutron electron proton

Answer 1

Derivation of de Broglie equation

According to Planck's quantum theory,
E= hv --------(I)

According to Einstein mass energy equivalence relation,
E= mc^2 ---------(ii)

So, On comparing (I) and (ii)
we have,

hv= mc^2
hc/lambda =h/mc. (lambda=wavelength)
Lambda=h/p. (p=momentum of moving particle)

Hope it helps.....
